Annular conveyor for hollow capsules

Abstract

The invention discloses an annular conveyor for hollow capsules. The annular conveyor comprises a rack, wherein the rack is provided with a material feeding device and a material distributing device; the material distributing device comprises a material storage cabin, a material conveying rotary plate, a capsule tray and a driving mechanism, the material storage cabin is arranged below the material feeding device, the capsule tray is used for supporting the material conveying rotary plate, and the driving mechanism is used for driving the material conveying rotary plate to rotate; the material conveying rotary plate is provided with at least one circle of hole positions for storing the hollow capsules, and a cleaning mechanism is arranged in the material storage cabin and is used for cleaning up hollow capsules which are not arranged in the hole positions or sweeping the hollow capsules into the hole positions; the cleaning mechanism comprises at least two cleaning brushes, the material storage cabin is separated into a cleaning area and a material stacking area by the cleaning mechanism, the cleaning area is provided with the cleaning brushes, the material stacking area is not provided with the cleaning brushes, a blocking wall is arranged in the material stacking area and is used for preventing the hollow capsules from entering the hole positions, the area, out of the blocking wall, of the material storage cabin is a conveyance area, the capsule tray corresponding to the conveyance area is provided with material discharging openings corresponding to the hole positions, and the hollow capsules are removed from the hole positions through the material discharging openings; an outlet of the material feeding device is arranged above the material stacking area.

Description

technical field [0001] The invention relates to a material conveying device, in particular to a hollow capsule annular conveying device. Background technique [0002] In recent years, with the rapid development of the pharmaceutical industry, China's pharmaceutical output value has exceeded one trillion yuan, of which my country's pharmaceutical capsules have accounted for 20% of the total pharmaceutical preparations. By the end of 2010, there were more than 3,000 approved capsule manufacturers, with an annual output of more than 100 billion gelatin hollow capsules, accounting for 30% of the world's hollow capsule market, and maintaining double-digit growth every year. [0003] In the prior art pharmaceutical hollow capsule production line, when the capsule body and capsule cap are closed, the capsule is sent out by a conveyor belt. The conveyor belt device has a complex structure, a large floor space, and high investment costs. And because the hollow capsule production lin...

Problems solved by technology

[0003] In the existing production line of medicinal hollow capsules, when the capsule body and capsule cap are closed, they are sent out by a conveyor belt. The structure of the conveyor belt device is relatively complicated, the floor area is large, and the investment cost is also high.

And because the hollow capsule production line will inevitably produce mechanical failures during the production process, the produced hollow capsules will inevitably have defects and waste products. The defects of the hollow capsules are mainly black spots and air bubbles on the surface, accounting for about 20% of the total. It varies from 1% to 3%, and the capsule waste must be separated from the genuine product before delivery to the pharmaceutical factory

If the conveyor belt device is irregular in the fabric of the hollow capsules, it will make it difficult to select the defects of the hollow capsules, and it is difficult to completely eliminate defective waste products
